Abstract
Description
Technical Field
[0001] The present application relates to the technical field of protective equipment, and particularly to a high-precision electronic chest protector for taekwondo. Background Art
[0002] Taekwondo is a sport mainly using hands and feet for fighting or confrontation. In order to protect athletes during competitions or training and prevent the ribs of athletes from breaking, taekwondo chest protectors are usually worn on athletes. Taekwondo chest protectors are protection devices that athletes often wear in current combat sports.
[0003] In traditional taekwondo combat competitions, scores are determined by the opponent attacking the opponent's protective gear, and usually, referees determine scores by observing the athletes' competitions and videos with the naked eye. Due to the problems of the referees' observation angles and video shooting angles, misjudgments may occur, which will affect the fairness and justice of the athletes' competitions and have deficiencies. Utility Model Content
[0004] In order to improve the problem that referees are prone to misjudge athletes' scores, the present application provides a high-precision electronic chest protector for taekwondo.
[0005] A high-precision electronic chest protector for taekwondo provided by the present application adopts the following technical solutions:
[0006] A high-precision electronic chest protector for taekwondo includes a shoulder pad, a front chest pad, and a back pad. A wearing opening is provided on the shoulder pad. The front chest pad and the back pad are symmetrically arranged with respect to the shoulder pad. The front chest pad and the back pad are both detachably arranged on the shoulder pad. A tightening component for adjusting the tension is arranged between the front chest pad and the back pad. Impact pressure sensing modules are arranged on both sides of the front chest pad and the back pad facing away from each other, and impact pressure sensing modules are arranged on both sides of the front chest pad and the back pad facing each other. Both the impact pressure sensing module and the impact pressure sensing module are electrically connected to a control system.
[0007] By adopting the above technical solutions, the wearer puts the shoulder pad on the neck through the wearing opening, and then fixes the front chest pad and the back pad on the front and back sides of the wearer through the tightening component. When the front chest pad and the back pad of the wearer are struck, the impact pressure sensing module and the impact pressure sensing module feedback the pressure change to the control system, thereby accurately feedbacking the score situation of the wearer and reducing the possibility of misjudgment by the referee.
[0008] Optionally, the impact pressure sensing module includes a base pad, and a number of pressure strain gauges electrically connected to the control system are laid on the base pad. A display screen electrically connected to the control system is arranged on the front chest pad.
[0009] By adopting the above technical solution, when the protection pad is struck, the striking force is transmitted to the pressure strain gauge on the base pad. The pressure strain gauge deforms and feeds back information to the control system. The control system displays the score value corresponding to the striking force on the display screen, reducing the labor intensity of the referee's score judgment and better reflecting the fairness and justice of the competition.
[0010] Optionally, a protection pad is provided on the chest protection pad, and the base pad and the pressure strain gauge are located between the protection pad and the chest protection pad.
[0011] By adopting the above technical solution, the possibility of the impact pressure sensing module being damaged by direct contact with an external force is reduced, and at the same time, the striking force received by the wearer is weakened.
[0012] Optionally, the impact pressure sensing module includes an elastic bladder provided on the opposite side of the chest protection pad and the back protection pad. The open end of the elastic bladder is provided with a gas flow rate sensor electrically connected to the control system.
[0013] By adopting the above technical solution, when the chest protection pad or the back protection pad is struck by other athletes, the impact generated by the strike causes the chest protection pad or the back protection pad to squeeze the elastic bladder. The elastic bladder deforms and discharges the air inside it. The rapid discharge of the air in the elastic bladder triggers the gas flow rate sensor. The gas flow rate sensor feeds back information to the control system, and the control system determines that the strike result is valid, reducing the possibility that the pressure strain gauge on the chest protection pad or the back protection pad is triggered due to the wearer's own movement, which is beneficial to improving the accuracy of the competition result.
[0014] Optionally, the tightening assembly includes a tightening rope provided on the chest protection pad, a loop belt is provided on the back protection pad for the tightening rope to pass through, and an anti-loosening member for fixing the tightening rope on both sides of the loop belt is provided on the tightening rope.
[0015] By adopting the above technical solution, the wearer pulls the tightening rope to reduce the distance between the chest protection pad and the back protection pad, and then fixes the tightening rope through the anti-loosening member to adapt to wearers of different body types.
[0016] Optionally, the anti-loosening member includes an outer cylinder. An outer wire hole for the tightening rope to pass through is provided on the outer cylinder. An inner cylinder is coaxially and slidably arranged along the axis inside the outer cylinder. An inner wire hole for the tightening rope to pass through is provided on the inner cylinder. A screw rod is coaxially and rotatably arranged on the inner cylinder, and the screw rod is threadedly connected to the outer cylinder.
[0017] By adopting the above technical solution, after the wearer adjusts the distance between the front chest pad and the back pad, the wearer turns the screw rod, and the screw rod pushes the inner cylinder to slide, so that the inner wire holes on the inner cylinder are staggered from the outer wire holes on the outer cylinder, thereby achieving the effect of locking and fixing the tightening rope.
[0018] Optionally, the cross-section of the front chest pad is arc-shaped.
[0019] By adopting the above technical solution, the front chest pad better meets the requirements of ergonomics and improves the protection effect on the side parts of the wearer.
[0020] Optionally, a connecting band is provided on the shoulder pad, a connecting hole for the connecting band to pass through is provided on the front chest pad, and a magic tape is provided on the connecting band.
[0021] By adopting the above technical solution, when the pressure strain gauge on the front chest pad or the back pad is damaged, the wearer can quickly replace the new front chest pad or the back pad, and the wearer does not need to replace the whole chest protector, which is beneficial to reducing the maintenance cost.
[0022] In summary, the present application includes at least one of the following beneficial technical effects:
[0023] 1. The wearer puts the shoulder pad on the neck through the wearing port, and then fixes the front chest pad and the back pad on the front and back sides of the wearer through the tightening assembly. When the front chest pad and the back pad of the wearer are struck, the impact pressure sensing module and the shock pressure sensing module feedback the pressure change to the control system, so as to accurately feedback the score of the wearer and reduce the possibility of misjudgment by the referee;
[0024] 2. When the protection pad is struck, the striking force is transmitted to the pressure strain gauge on the base pad, and the pressure strain gauge deforms and feeds back the information to the control system. The control system displays the score value corresponding to the striking force on the display screen, reducing the labor intensity of the referee's score determination and better reflecting the fairness and justice of the competition;
[0025] 3. When the front chest pad or the back pad is struck by other athletes, the impact generated by the strike causes the front chest pad or the back pad to squeeze the elastic bladder, the elastic bladder deforms and discharges the air therein, and the rapid discharge of the air in the elastic bladder triggers the gas flow rate sensor. The gas flow rate sensor feeds back the information to the control system, and the control system determines that the strike result is valid, reducing the possibility that the pressure strain gauge on the front chest pad or the back pad is triggered due to the movement of the wearer himself, which is beneficial to improving the accuracy of the competition result.
